IMPROVEMENT IN COMBINED PENCIL-SHARPENERAND ERASER.

Specification forming part of Letters Patent No. 204,169, dated May 28,1878; application iled April 26, 1878.

To all whom 'it 'may concern.' t

Beit known that I, WILLIAM SELLERS, of Haverhill, in the county ot' Essex and State of Massachusetts, have invented a Combined Pencil-Sharpener and Eraser, of which -the following is a specification:

The object of my invention is to produce a sim ple, cheap, and convenient device for sharpening lead and slate pencils and erasing marks made by the same; and the invention consists in the combination, in one implement of small dimensions, of a device for cutting the pencil above the point, also one for sharpening the point ofthe pencil, an eraser for erasing peucil-marks, and also one for erasing marks on a slate made by a slate-pencil.

The accompanyingr drawing is a perspective- View of an implement embodying my invention.

A represen ts the base of the implement, having at one end a standard, G, having a hole through its center, in Which is fixed a piece ot' india-rubber, F. At the opposite end is a conically-shaped piece, D, provided With a knife or cutter, d, extending longitudinally through the same. The small end of the cone D is made large enough to allow the point of the pencil to extend through the end,the knife or cutter being intended to cut the wooden portion of the lead-pencil, and the larger portion ot' the end ofthe slate-pencil.

In the ordinary peucil-sliarpeners, made atter the style shown in my device, the knife is made to cut the point of the lead as Well as the wood. This very frequently results in breaking the lead, and fails to make afme point. By making the small end of the cone D large enough to admit of the end ofthe lead passin g through I obviate this difficulty', and in order to sharpen the point of the lead I arrange above the Sharpener D a V-shaped grooved device, E, having serrated or roughened surfaces H, so that by drawing the pencil-point over the same a fine edge will be given lto it. The grooved device also serves to hold the scrapings of the pencil, and thus avoids soiling the hands.

On the bottom of the base A is'secured a piece of wash-leather or other soft material, B, for erasing the marks on a slate.

The metallic portion of the implement, with the exception ofthe cut-ter d, may all be cast in one piece. -It is designed for u se on the desk, and is particularly adapted for the use -of children at school.

,WILLIAM SELLERS.
